Samuel Dalembert on the block?

The Dallas Mavericks signed Samuel Dalembert in July since they were lacking someone on the roster to defend the rim as a shotblocker, however he is not filling that need as he is only averaging 1.3 per game. Dalembert has not done enough in the eyes of head coach Rick Carlisle and now he is a backup since DeJuan Blair has been promoted to the starting position. Can Dalembert get the stating spot back? Maybe, but unlikely.
